This two sides are made in mark software, the length on two sides in the middle of mark software is determined according to foursquare size
Degree and position.
5032nd, adjusting lifting body highly makes the mark location of the straight line units overlap with laser spot；
The height that lifting body is adjusted by controller makes the mark location of two lines burnt with the laser of laser marking head
Point overlaps.So as to ensure mark on same level height, it is to avoid as mark face inclines, mark location is inclined
From causing the change of mark figure and mark distance, make laser spot change, cause mark defocusing.
5033rd, mark is carried out to the straight line units；
Laser marking head carries out mark using telecentric lens to two lines, obtains two mark lines such as Fig. 6 a.
5034th, rotary shaft is rotated and mark three times is carried out to the straight line units, rotate the rotation every time
90 degree of axle.
Rotary shaft is rotated by 90 ° and postrotational two lines are carried out with mark three times according to step 5033, according to
The secondary mark figure formed such as Fig. 6 b-6d.
After the mark figure for completing Fig. 6 d, mark figure is treated to be formed in Fig. 6 h, needs are being beaten
The position on two sides is changed in mark software, and repeat the above steps 5031-5034 are sequentially formed such as Fig. 6 e-6h
Mark figure.Finally give and treat mark figure such as Fig. 6 h.
The laser marking method that the present invention is provided, by mark workpiece is arranged in inclined plane, beats workpiece
Mark face and laser lens plane at an angle, arrange the angle for 20 degree, can make to treat the mark edge of work and
Mark face is in 90 degree, eliminates the bottom deformation caused because of taper angle, installs irregular problem.By rotation
The rotation of rotating shaft and the adjustment of linear stage, can mark go out the center pair being made up of vertical flare angle straight line units
Claim figure, and realize to each mark cohesive position and treat the precision controlling of mark dimension of picture.
Finally illustrate, above example only to illustrate technical scheme and unrestricted, although
The present invention is described in detail with reference to preferred embodiment, it will be understood by those within the art that,
Technical scheme can be modified or equivalent, without deviating from technical solution of the present invention
Objective and scope, which all should be covered in the middle of scope of the presently claimed invention.
